4.2 Power Source
The CSM requires power from an external source to operate.
When testing OBD-II/EOBD vehicles, the CSM is powered by the vehicle when
connected to the data link connector (DLC).
When testing OBD-I vehicles that do not have battery power (B+) at the DLC, the
CSM is powered by connecting a power cable directly to the optional OBD-I
manufacturer specific adapter, see To connect the CSM to OBD-I vehicles: on
page 36.
When performing a CSM firmware update, the CSM should be powered by USB
connection directly to the diagnostic tool, see Firmware Updates on page 39.
